命题点1动词不定式(to do something.)的用法
动词不定式可作主语、表语、宾语、定语、状语和宾语补足语。
1.作主语。不定式作主语往往用形式主语it代替，作为句子真正主语的不定式则后置。常用句型：It?is 加形容词加(for/of) sombody.to do something.。如：
It?is nice of you to take pictures for us. 你真好，给我们照相。
2.作表语。常放于系动词be之后。如：
To see is to believe. 眼见为实。(百闻不如一见。)
3.作宾语。常见的后面接动词不定式作宾语的动词有：

承诺做如：I would like to have a cup of tea.我想喝一杯茶。
4.作定语。动词不定式作定语时，要置于被修饰的名词之后，作后置定语。如：
I am not free now. I have lots of things to do. 我现在没有空。我有很多事要做。
5.作状语。如：
